This snorkelling guide for Koh Lanta will cover everything you should know to make the most of your snorkelling adventure in this tropical paradise.

 

Why is Koh Lanta a Snorkeling Hotspot?

Koh Lanta, located in the Andaman Sea off the coast of Thailand, is a tropical island known for its stunning beaches, flourishing greenery, and vibrant marine life. Snorkelling is one of the top activities for tourists visiting this idyllic destination, as the crystal-clear waters surrounding Koh Lanta offer an unparalleled opportunity to explore the colourful world beneath the surface.

Koh Lanta boasts abundant marine life, its warm waters teeming with colourful coral reefs, tropical fish, and other fascinating creatures. The island is surrounded by several smaller islands, each with unique snorkelling spots, making it a haven for snorkelers of all skill levels. Whether you are a novice or an experienced snorkeler, Koh Lanta offers a variety of underwater landscapes to explore, from shallow coral gardens to deeper reef slopes and even the chance to spot majestic sea turtles and leopard sharks.

 

Best Snorkeling Locations

Hin Daeng and Hin Muang: These two dive sites, located a short boat ride from Koh Lanta, are renowned for their pristine coral reefs and the opportunity to spot larger marine species such as whale sharks and manta rays. Snorkelers can enjoy swimming alongside colourful fish, turtles, and even reef sharks, making it a must-visit spot for experienced snorkelers.

Koh Rok: This picturesque island in the Koh Lanta National Marine Park is a snorkeler's paradise with crystal-clear waters, vibrant coral reefs, and diverse marine life. Snorkelers can expect to see various tropical fish, including parrotfish, angelfish, butterflyfish, and the occasional blacktip reef shark.

Koh Ha: Another popular snorkelling spot in the Koh Lanta National Marine Park, Koh Ha is known for its beautiful coral gardens and clear visibility. Snorkelers can swim among colourful corals and fish, including damselfish, triggerfish, and clownfish.

 

Safety Tips

Always snorkel with a buddy: Snorkeling is fun and exciting, but it's crucial never to snorkel alone. Always have a buddy with you to watch out for each other and provide assistance if needed.

Be aware of the currents: Some snorkelling spots around Koh Lanta can have strong currents, especially during the monsoon season (May to October). Therefore, you must be aware of the current conditions and only snorkel in areas where you feel comfortable and safe.

Respect the marine environment: As responsible snorkelers, protecting the fragile marine ecosystem is crucial. Avoid touching or stepping on coral reefs; never feed or chase marine animals. Leave nothing behind but footprints, and take only pictures and memories with you.

 

What You'll Need

Before you embark on your snorkelling adventure in Koh Lanta, have the right gear to ensure a safe and enjoyable experience. If you book a tour, they usually have all these essential items. If you go on your own, here's what you'll need:

  • Snorkel mask: A properly fitting one is crucial for a comfortable and clear underwater view. Look for a mask with a silicone skirt that fits snugly around your face and a tempered glass lens for better visibility.
  • Snorkel: Choose a snorkel with a comfortable mouthpiece and a splash guard that stops water from entering the snorkel when on the surface.
  • Fins: Fins are essential for efficient water movement and reducing fatigue. Make sure they fit well and are comfortable to wear.
  • Rash guard or wetsuit: Depending on the season and water temperature, you may need a rash guard or wetsuit that protects your skin from the sun and marine life.
  • Sunscreen: Opt for a reef-friendly sunscreen that won't harm the marine ecosystem.
  • Waterproof bag: A waterproof sack will keep your belongings safe and dry while snorkelling.
  • Towel: You might want to bring a towel to dry when out of the water or sit on when you're onshore.
  • Water and snacks: Stay well hydrated and energized with water and snacks during your snorkelling adventure.

 

Best Times to Go

Koh Lanta is a year-round snorkelling destination, but the best time to go largely depends on the weather and water conditions. The dry season from November to April offers calm seas, clear skies, and excellent visibility underwater, making it the peak season for snorkelling. During this time, the water is warm and teeming with marine life, including colourful fish, turtles, and sharks.

The rainy season from May to October may experience rough seas and limited visibility due to rain runoff. Still, it can also offer unique snorkelling opportunities with fewer crowds and lower prices. The water temperature is still warm, and the coral reefs are at their most vibrant during this time.
